The SL-IV / PLUS waterjet pump provides output water pressures up to 4,100 bar (60,000 psi) for ultrahigh-pressure waterjet cutting, hydrobrasive cutting, cleaning, surface preparation, etc. This manual provides information for installation, operation, and maintenance of the SL-IV / PLUS waterjet pump. 1.1 Description The SL-IV / PLUS waterjet pump is a self-contained functional unit. The major assemblies within the SL-IV / PLUS intensifier are single (or optional redundant) high-pressure intensification assemblies, single or dual high- pressure attenuator(s), a motor and hydraulic pump assembly, an oil cooling/filtration system, a low pressure water booster pump with low pressure water filtration, a fail-safe high-pressure venting valve, and an integrated NEMA 12 electrical control enclosure. .jpg Letter Connection U Cutting Water OUT ...3/8” HP V Plant Air ...................¼” NPT W Cooling Water IN.......½” NPT X Cooling Water OUT ...½” NPT Y Cutting Water IN.......½” NPT Z Drain........................½” NPT 01/2004 1 - 1 SECTION 1 INTRODUCTION NOTE KMT Waterjet Systems recommends approx. 950 mm / 36” minimum clearance around intensifier for maintenance.

The high-pressure intensification assembly is mounted on a drip pan on the frame top at a convenient height for performing routine maintenance. All components requiring routine maintenance are easily accessible through self-levitating hinged transparent covers or removable protective panels covering the sides of the lower frame. The high-pressure intensification assembly can be easily and quickly removed from the intensifier base if deemed desirable or necessary for maintenance. 01/2004 1 - 2 SECTION 1 INTRODUCTION 1.1.1 Features • Variable displacement, pressure compensated axial piston hydraulic pump. • Inlet water pressure booster pump and filtration system with 10-micron high capacity filter. • High efficiency oil-to-water heat exchanger and cartridge oil filter in an oil circulation pump circuit separate from the main hydraulic pump circuit. • Thermostatically controlled water-cooling system for optimum hydraulic oil temperature stability. • Integrated electrical controls include a standard wye-delta motor starter to minimize motor inrush current at startup. • High-pressure safety dump valve. • Dual pressure compensators on the main hydraulic pump allow manual or program controlled selection of two different output pressures. • Optional electronically controlled continuously variable hydraulic pressure control may be integrated into the host CNC unit for real-time pressure control. • TUV approved high-pressure attenuator for smooth high-pressure water delivery. • TUV approved pre-set hydraulic relief valve eliminates the need for rupture disc overpressure protection. • Microprocessor control with diagnostic capability and multi-language touch screen operator interface. • Cutting water solenoid-operated shutoff valve. • Inlet water pressure and booster pressure switches insure that there is adequate supply water pressure to the SL-IV / PLUS high-pressure intensification assembly to prevent water starvation damage. • Separate water and oil drip pans for cleanliness. • Remote control electrical interface connector port. • Remote diagnostic communication option. 1.2 Functional Description The HP intensification assembly uses a hydraulically driven piston operating in electrically reversed reciprocating mode, coupled at both ends to high-pressure intensification cylinders. The HP intensification cylinders extrude high-pressure water alternately, while the HP attenuator minimizes fluctuations in the output water signal. The intensification ratio is 20:1 with maximum hydraulic pressure set at 3,100 psi. 1.2.1 Functional Features • 4,150 bar (60,000 psi) operating pressure • Electronic reversing 01/2004 1 - 3 SECTION 1 INTRODUCTION • 24vdc control logic • Built-in high-pressure water leak detection diagnostics • Standard dual pressure control facilitates hole piercing and kiss cut applications • Exclusive long, slow plunger stroke • Cartridge type hydraulic seals • Low pressure water booster pump and filtration • Reduced cooling water requirements • Choice of English, German, Spanish, French, Swedish and Italian readouts as standard • Meets CE requirements 01/2004 1 - 4 SECTION 1 INTRODUCTION 1.3 Worldwide Product Support The KMT Waterjet Service Department serves the customer, by providing: Supervision of equipment installation, start up, and training for the number of days specified in the quotation, and per approved project.
